Letters Patent No. 91,510, dated J one 22, 1869.

/ IMPROVEMENT IN VELOCIPEDES.

The Schedule referred toin these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, Gnonc BERGNER, of Washington, Franklin county, State of Missouri, have invented a new and useful improved Velocipede, of which the following is a full, clear, and exact description,'reference being had to the annexed drawing, making a part of this specification, in \which Figure 1 represents a side view of my invention, with a portion broken out.

Figure 2 represents a top view of same, also with a portion broken out.

' Similar letters indicate like parts.

It consists of two concentric wheels, A B, fig. 1, A,

. fig. 2, the outer one having a broad tread, while the inner one is somewhat narrower.

In the periphery of B are placed friction-wheels a a a, a fig. 1, a, fig. 2, having central flanges, as seen at z, figl'2, running in the'clianuel 'u, fig. 1, cut in the rim of A. I

This channel is out deep enough to admit a series of cogs, 1, 2, 3, 8m, below and out of reach of the flange of the fi-iction-wheels.

Across the centre of B is placed a frame, D, its extremities fixed in the rim of B, one being forked, as seen in fig. 2.

These forks serve as bearings for a double spurwhcel, E, fig. 1, E E, fig. 2, and for a single spur-wheel, F, figs. 1, 2, which is made broad, and occupies the space between E E. l

On this wheel are two pinions o o, fig. 2, 0, fig. 1, one on either side, gearing with E E, while Fengages with the cogs in the rim of A.

Two cranks, m 'm, fig. 2, an, fig. 1, are attached to the shaft 12, fig. 2.

These several wheels are so arranged'as to leave room for the saddle, or seat H in the centreof the 7 wheel and midway between the extremities of D, the

front of the saddle s being-made to curve over E, so as to protect the rider.

Two supports, t t, fig. 2, t, fig. 1, are placed under the saddle, and are slotted at p p, 1) only being shown in fig. 1, so as to receive the'pivot' of the stirrups It It, fig. 2, k, fig. 1, made of sheetmctal, curved at one end, as seen, and which are made adjustable in these slots by means of thumb-screws no, fig. 2.

A hood,'G, of leather, or other suitable material,

stretched over a frame, as seen, is hinged above the seat, and by the cord x passing over a pulley in the rim of B, not shown, is raised or lowered at pleasure.

Around the outer wheel are placed two rubber tires, w 10, fig. 2, w fig. 1.

To give an idea of the dimensions of the various parts, I would recommend that, for an inner wheel, six feet in diameter, the tread of the outer wheel should'be three or four inches, the drivipg-wheels about twenty inches, the follower from sixteen to twenty, the pinions from four to six, and the friction-wheels six inches in diameter; but of course I do not limit myself to any of these dimensions, as they maybe varied at pleasure.

The rider being in the saddle, and bending slightly, so asto throw the centre "of gravity forward, can, by

: turning the cranks, easily start the machine, after which he can sit upright.

In going down hill he would of course lean back, and the stirrups swinging freely on their pivots, his seat will be as easy, and he can control the speed as advantageously as in any other position.

Should it rain, or the sun be too hot, the hood can be dropped by simply loosening the cord, and as easily folded up again when desired.

If necessary a rim of sheet-iron may be placed around the upper edge of A, so as to keep the dirt from the inside, and so, perhaps, interfere with the gearing.

To guide the machine, it is onlynecessary to incline the body to one side or the other, or if this should not be sufiicient, the foot may be allowed to impinge on the ground.

I, do not claim to be the inventor of the singlewheeled velocipede, for I am well aware that such have been inuse heretofore; but

\Vhat I do claim as my invention, and desire to secure by Letters Patent, is-

A velocipedc combining the wheels E, E, and'F, pinions 0 o, cogs 1, 2,3, 850., adjustable stirrups It i, coucentrio wheels A and B, provided with friction-rollers a a a a and seat H, all constructed, arranged, and operated substantially as and for the purpose shown and specified.
